PAVIA SHUTTLE QUILL OR COP HOLDER Filed Feb. 28, 1955 ma a 6 EU ma F E wn mas s s ATTORNEYS Patented July 2, 1935 UNITED STATES PATENT OFFICE 2,007,097 SHUTTLEQUILL on cor HOLDER Luigi Pavia, Allentown, Pa. Application February 28, 1935, Serial No. 8,751 6 Claims. (01. 139-206) This invention relates to cop holders or quills to be used in loom shuttles, an object being to provide an improved construction wherein the desired size and form of head may be provided for a paper or metallic holder.

Another object of the invention is to provide a head for a' combined paper and metallic cop holder wherein a desired thickness of head is secured.

A further object, more specifically, is to provide a head for a paper cop holder having a metal sleeve at one end merging into an annular flange, the structure being such that the superimposed or added head surrounds one end of the holder and encloses the flange so as to make a substantially rigid construction and one having the desired height and thickness to fit into a conventional loom shuttle.

In the accompanying drawing- Figure 1 is a plan view of a loom shuttle with a quill embodying the invention shown mounted therein;

Fig. 2 is an enlarged fragmentary sectional view through Fig. 1 approximately on the line Fig. 3 is an appreciably enlarged vertical longitudinal sectional view through the end portion of the quill or cop holder shown in Fig. 1;

Fig. 4 is a view similar to Fig. 3, but showing a modified construction of the quill, and

Fig. 5 is a view similar to Figs. 3 and 4 but showing a further modified construction of the quill.

Referring to the accompanying drawing by numerals, I indicates the shuttle body which may be of any desired kind, as, for instance, a construction that is well known on the market and one that is provided with jaws 2. The jaws 2 are provided to interlock with the head of the quills or cop holders. Where the quills or cop holders are made from wood, the head is usually integral and of the proper thickness to fit nicely within the jaws 2, whereby the quill or cop holder cannot independently move longitudinally in the body I Wooden quills or cop holders now on the market are provided with enlarged heads which fit properly within the jaws 2, but there is a less expensive quill or cop holder on the market which is made of paper and provided at one end with a metal sleeve merging into a flange. As shown in Fig. 3, 3 indicates the paper cop holder, which is provided with a metallic sleeve 4 merging into a flange 5. The parts just described are old and well known, but it will be seen that the flange 5 is composition of filler paratively thin and when placed between the jaws 2 thereis an appreciable lost motion. This is objectionable for many reasons, particularly in view of the fact that as the shuttle moves back and forth the flange 5 will forcefully strike 5 against certain parts of the jaws andbecome worn or bent out of shape. Notwithstanding this objection, large numbers of these quills or cop holders are used because of the fact that they are very inexpensive. 10

To obviate the objection to a thin flange which acts as a head, the present invention contemplates means for thickening the flange 5 as far as the breaking of the quill is considered. As shown in Fig. 3, there is provided a filler block 6, which may be wood, fiber, or waste of any kind, or, if desired, it could be made of paper or metal, although wood has been found to be the most desirable. A ring 1 coacting with the filler block or ring 6 and the flange 5, forms what may be termed the complete head 8. The ring I has its peripheral surface merging into inwardly extending flanges 9 and i0, flange l0 preferably contacting with the sleeve 4. The flanges 9 and ID are pressed toward each other to such an extent as to firmly pinch all the parts together, whereby there will be no lost motion. As the wood of ring 6 is somewhat resilient and also as the flange 5 is somewhat resilient, the pressing of the flanges 9 and slightly compressthese parts and thus when the pressure is removed these parts are under tension so that the ring is resiliently and frictionally held against accidental movement. In this way the head of the quill is enlarged until it is of the size of the conventional wood head which properly fits into the jaws 2 of any of the standard shuttles now on the market. By providing a superimposed or assembled head 8, as shown in Fig. 3, the back and forth movement of the shuttle will not cause an independent movement of the quill or cop holder, as the head fitting properly in the jaws 2 prevents any such movement.

While the quill or cop holder 3 is commonly made of paper as now put on the market, it is evident that it could be made of other material without departing from the spirit of the invention and the head 8 applied thereto as just described.

In Fig. 4 will be seen a quill similar to that shown in Fig. 3 except that the flllerblock. 6' is arranged on the opposite side of the flange 5 and the ring 1' is adjusted to meet this changed block 6'. This arrangement [0 toward each other will 30 secures the same result as shown in Fig. 3, namely, an enlarged head which will properly coact with various standard shuttles and which will also protect the flange 5.

In Fig. 5 a further form of head is shown to that illustrated in Figs. 3 and 4. In this figure there are provided two filler blocks, namely, filler blocks H and i2.

I claim:

1. The combination with a quill or cop holder having a radiating flange at one end, of means forming a head for the quill, said means comprising an enclosing ring formed substantially U-shaped in cross section at all points, and a" filler arranged between said flange and one side portion of said ring.

2. A quill or cop holder for loom shuttles, comprising a hollow body formed with a flange at one end, and means forming a head surrounding said flange, said means comprising a ring having a peripheral portion and a pair of in wardly extending flanges, one flange overlap-, ping and contacting with the flange on said body, while the other flange is spaced therefrom, and a substantially resilient ring arranged between said other flange and the flange of said body.

3. A quill or cop holder for loom shuttles, comprising a quill body formed of a desired material, a metal sleeve for one end of the body, said sleeve at the end having a radiating flange, an annular filler block arranged against said flange, and a metal ring U-shaped in cross section enclosing the filler block and the flange on all sides except the interior.

4. A quill or cop holder for loom shuttles,

comprising a quill body, a metal sleeve arranged on each end of said quill body, said sleeve at the rear end having a radiating flange with the outer part bent back upon itself, a filler block arranged against said flange on the side opposite the sleeve, and a clamping ring substantially U-shaped in cross section at all points, said clamping ring partly enclosing the filler block and flange and acting to clamp the filler block against the flange. 5. A quill or cop holder for loom shuttles, comprising a. quill body of paper formed with a large end, a metal sleeve fitting over said large end, said sleeve at one end having a radiating flange, a filler block divided into two parts, one part being arranged on each side of said flange, and a clamping ring having inwardly extending flanges for clamping said parts against said radiating flange.

6. A quill or cop holder for loom shuttles, comprising a quill body having a radiating flange at one end, and means forming a head surrounding said flange, said means comprising a ring formed with a peripheral traction portion merging at the sides into inwardly extending flange members, and a widening packing ring arranged between said radiating flange and one of'the inwardly extending flanges of said first mentioned ring.
